In August, the Denver City Council proposed an ordinance to reduce its cooperation with the Department of Homeland Security to bolster its bona fides as a “sanctuary city.” Denver’s latest progressive hectoring, prideful virtue signaling, and puerile chest-thumping is icing on the cake.

By whatever delineating characteristics are applied—there is no legal definition—Denver has been a sanctuary city for about 20 years. Soon it will be held accountable for its irresponsible conduct, either by the Trump administration or by a growing legion of crime victims.
